For vertical hinged door.Hermatic door is mounted on the side of cabinet by hinge, constitutes the door that (left outside open or right external-open) is opened outward, and
It is fixed on another side of cabinet by locking device, closes hermatic door tight.
However, existing hermatic door can not be closed tight closely.It traces it to its cause, on the one hand, in frequent routine switch gate process
Middle locking device usually fails；On the other hand, since flat-open type hermatic door is lateral unlatching, after locking device failure, hermatic door
There is no any device that can maintain sealing.Hermatic door, which can not be closed tight, will lead to problems, firstly, in wet environments such as fields
Under, recording card is easy moisture damage deformation, can not accurately record production history.Secondly, under strong wind meteorological condition,
The recording card of box house cannot be close to panel, will also result in recording card inaccuracy.
Utility model content
The purpose of this utility model is that: for the flat-open type hermatic doors of existing dual bellows differential gauges, there are illusive
Problem, providing a kind of hermatic door is plug-type dual bellows differential gauges.The hermatic door of the dual bellows differential gauges is plug-type
Door, compared to more firm characteristic.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
A kind of hermatic door is plug-type dual bellows differential gauges, including cabinet and hermatic door, the two sides of box opening are set
It is equipped with sliding slot, the opening of two sliding slots is opposite, and hermatic door is slidably inserted between two sliding slots；And between hermatic door and cabinet
It is additionally provided with, the locking device for being locked at hermatic door after hermatic door is closed on cabinet.This programme designs hermatic door
Be it is plug-type, optimize the switch direction of hermatic door, can effectively to dual bellows differential gauges inside correlation delicate metering component, record
Card is protected.And device is locked, it can achieve the purpose of dual-seal.Even if locking device failure or operator
Forget to close tight, due to the peculiar structure of plug-type hermatic door, its own self weight, which can be realized, to be automatically closed, and then reaches dual close
The purpose of envelope.
Preferably, the bottom end of sliding slot is provided with limited block, and box opening is completely covered after closing hermatic door.It is logical
The position for crossing limited block limitation hermatic door, keeps the sealing effect of cabinet more preferable.
Preferably, track groove is provided in sliding slot, hermatic door two sides are provided with protruding shaft；Protruding shaft in track groove on
Lower slider, 90 ° of overturning is placed on above cabinet after opening hermatic door.Convenient for instrument operation personnel when replacing recording card,
Open the operation of hermatic door.
Preferably, locking device includes the first locking hole of setting on the chute, and is arranged on hermatic door
The second locking hole；The first locking hole is mutually matched with the second locking hole after closing hermatic door, and is sequentially inserted into the by pin
Two locking holes and the locking of the first locking hole.It is cooperated by locking hole and pin, locks hermatic door and cabinet, structure letter
Single, locking effect is stablized, and easy to operate.
Preferably, handle is provided on hermatic door.Be more convenient for instrument operation personnel to hermatic door carry out day it is normally opened
The operation opened and closed.
Preferably, hermatic door uses transparent plastics material.Instrument operating condition is observed convenient for instrument operation personnel,
Reduce the switching frequency of hermatic door.
Preferably, gasket is provided between hermatic door and cabinet, gasket matches hermatic door with cabinet compression
It closes.Gasket can prevent rainwater etc. from entering in cabinet.
Preferably, gasket uses rubber material.Rubber material processing technology thereof is at low cost, and material cost
It is low, and there is preferable sealing effect.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the utility model
Be: hermatic door is designed as plug-type by the utility model, optimizes the switch direction of hermatic door, can be effectively to dual bellows differential gauges
The protection of internal correlation delicate metering component, recording card.So that it is guaranteed that oil gas adopts the accuracy of defeated metering, instrument is also increased
Durability.Whether normally there is great importance to the production status and the defeated system of pipe that judge oil/gas well, is also oil/gas well
Lower step development plan establishment provides reference role.
